Java object i use in scala are getting created several times -

i work play framework 2.5 , use several java classes trough scala in templates. create object 1 times

@import myclass; @foo = @{new myclass(bar)} 

with code, contructor of myclass not called (i have put debug output in constructor check call of it)

now use function of java class like

@foo.getmesomebar() 

somewhere in template. now, constructor called. problem: every time use function of class in same template, constructor called.

the same problem occurs, if pass scala variable template like

@othertemplate(foo) 

every time foo used in othertemplate constructor called.

is desired behavior? if yes, why? if no, how can avoid it?

edit: if create myclass object in controller , pass there templates constructor called 1 times. in cases if have create myclass in template or have change lot of classes.

according documentation, should not use @foo = @{ ... } define reusable value. preferred way do

@defining(new myclass(bar)) { foo =>    @foo.getmesomebar()    ...    @othertemplate(foo)  } 

your way may have unexpected results, such re-running code in block every time called.
